The European Commission has proposed extra tariffs -- some as high as 100 percent -- on a range of U.S. goods in retaliation for new U.S. steel import duties, a commission spokesman said Saturday. The proposal was presented to the European Union Council of Ministers and will be given to the World Trade Organization by May 17. Once the WTO is notified, the revised tariffs would go into effect June 18, EC spokesman Eric Mamer said. The 100 percent tariffs will apply to items including some types of steel products and clothing, citrus fruit, gaming tables and linens. Some categories of steel products and clothing will be subject to lesser tariffs, along with such items as nuts and fruit, cardboard boxes and footwear. The revenue collected from the increases is expected to offset new tariffs on imported steel imposed by the United States. Canada and Mexico are exempt because they are partners in the North American Free Trade Agreement.
